Red mud in the Central Highlands is the waste sludge of the process of aluminum production from bauxite ore by the Bayer method. This paper uses red mud from the Central Highlands combined with chitosan to fabricate Fe3O4/Chitosan magnetic nanocomposites by co-precipitation with the help of ultrasonic techniques. Characteristic properties of Fe3O4/Chitosan magnetic nanocomposites were evaluated by analytical methods X-ray Diffraction, FT-IR, FESEM and BET. Kinetics of Cr(VI) adsorption in an aqueous medium of Fe3O4/Chitosan nanocomposites was studied through Langmuir, Freundlich isotherm adsorption models and assumed first and second-order kinetic equations, diffusion kinetics, and Elovich equations. The research results show that the Fe3O4/Chitosan magnetic nanocomposite system with a content of chitosan ranging from 3% to 15% corresponding to the saturation magnetization of the system reaching 32 – 58,2 emu/g. With a chitosan content of 10%, the nanocomposite system's maximum adsorption capacity with Cr(VI) in aqueous solution and specificity surface area (according to BET) reached 55.65 mg/g and 64.14 m2/g, respectively. The adsorption process of Cr(VI) on Fe3O4/Chitosan nanocomposites showed that consistent with Langmuir isotherm tissue, the assumed second order kinetics and Elovich equations.
